ELIZABETH A. ROBINSON, OF SCRANTON, PENN'SYILVANIA- VENTILATING- APPARATUS FOR- PULLMAN CARS.

Application filed February 25, 1922; Serial no; 535,193.

To all whom it may concern:

Be it known that I, ELIZABETH A.'ROBIN son, a citizen of thevUnited States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements inVentilating Apparatus for Pullman Cars, of which the following is. a

'cordance with my invention;

A still further object of the invention is to provide a device of this character which will add to rather than detract from the appearance of the car in which it is employed.

A still furtherobject is to provide a novel construction'of ventilator cowl whereby the air will be forced in at the ventilator openings regardless of the direction of motion of the train. 1 e

Other objects and advantages of the invention will become apparent throughout the course of the'following description.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts. throughout 7 Figure 1 isa fragmentary sectional view taken through a Pullman berth showing. a ventilating apparatus constructed in ac- Figure 2 is a section taken on the line 2.2 of Figure 1; I

Figure 4 is a front elevation of'the ventilator cowl; I 1

Figure 5 is afront elevation of the controlling device regulating the amount of incoming .air; and Figure dis a fragmentary detail view 0 the controlling device, parts being broken away. v Referring'now more particularly to the drawings, the numeral 10 indicates the wall of a Pullman car having formed therethrough, adjacent the upper end of the berth, an opening 11 in which issecured a cylinder 12 having its ends open.

Slidably mounted within thecylinder 12 is a ventilator regulator 13 comprising a cylinder having one end closed, as at 14, by an ornamental head plate disposed interiorly of the car and provided in theside wall thereof with spaced rows of spaced openings'15, the openings of each row be 7 ing ofthe' same size and the openings of thedifferent rows being of different slzes, thesmallest openings being arranged near- "70. est the closed end .1 1 and the size of the openings ofthe rows increasing as the distance from thehead increases. Secured to the regulator 13 1s asprmg 16 extending through a slot 13 formedin the wall of the regulator and provided withindentaranged about therows of openings 15 these indentations being adapted for selective en gagement with a' stop pin 18 whereby the regulator is resiliently'held in any desired adjusted position, the spring] 16 yielding to permit movement of the regulator when desired. The regulator 13. and the cylinder 12 have coacting means preventingrotation of the regulator and limiting the movement of the regulator: within the cylintions17 corresponding in number and ari der, this coacting means being indicated at 19 as a pin and slot engagement It is further', pointed out that the pin'and slot en'- gagement, including the pin 18, likewise serves to prevent rotationof the regulator L 13 within the cylinder. It will thus .be seen that thepin 18 serves as a single means carried by the tube and coactin'g with the regulator, for limiting the sliding; movement of the regulator-preventing rotation regulator in adjusted positions at points intermediate the' flimit of its movement.

Secured to the exteriorv surface of the car as by meansx'of an attaching flange 20 i I -of the regulator and for maintaining the loo 5 about the opening 11fis a ventilator cowl 21 v of a construction such that it will, .with-v out shifting the regulator thereof, direct a'u. intoithe open end of the cylinder 12 and regulator 13 regardless of thedirection-of movement of the train In the presentin stance this is attained-iby the employment upon the cowl 21 of a dependinglfiange 22 spaced from the sidewall of the car, and

a flange 23 upon the opposite sideof the i.

cowl arranged adjacent the side of the car.

When the train is moving in one direction the air passing between the flange 22 and the side of the car will abut the flange 23 and be directed into the opening. l Vhen moving in the other direction the air passing by the flange 23 will engage the flange curtains by means of which the occupant of the berth is shielded from the aisle, the eurtain'25 being provided with the usual flap attachment 26. To this flap attachment, if the flap be arranged interiorly of the curtain, and to the curtain 25, if the flap be arranged exteriorly of the curtain, is secured, as by means of an attaching flange 27, a ventilating device 28. This device comprises a plate 29 adapted to face the aisle and having upon its outer face the indicia 29 l11dl eating the number of the berth to which it is applied. The plate 29 has an annular flange 30 upon which the securing flange 27 is formed and in this flange 3O arev formed ventilator openings 31, the curtain 25 or curtain flap 26, as the case may be, being provided with an opening 26 coinciding with the interior of the flange 30 so that the interior of the berth is in communication with the interior of the flange and accordingly air can move from the berth through the openings 31 into the aisle of the car and so pass out through the ventilators. The curtain 24 is provided with an opening 32 through which the ventilating apparatus 28 maybe extended and the curtain 25 or flap 26, as the case may be, is likewise provided with an. opening 33 through which the ventilating device exs ten'ds- The exterior portion of the curtain 25 is provided with a plate 3% having an opening 35 formed therethrough through which may be extended a turn-button fastener 36 which is secured to thecurtain 24s tosecure the curtain in closed position and maintain the ventilating device with the openings thereof at the aisle side of the closed curtain.

In the use of my device when the occupant of the berth desires to increase or decrease.

the amount of air entering the berth from the exterior of the car this may be accomplished by shifting the regulator 13 either in or out, as the case may be. Moving the regulator inwardly exposes more openings interiorly of the car through which the air directed'inwardly of the flanges 22 and'23 may passand conversely moving the regulator outwardly decreases the number of openings exposed. The air passed from the ventilator openings passes through the berth incense and out through the openings of the ventilator device 28 into the aisle of the car where it may pass out through the usual ventilators provided at the upper structure of the car, which form no portion of my invention and are accordingly not h rein shown.

From the fore oing it is believed to be obvious that a ventilator apparatus con structed in accordance with my invention is particularly well adapted for the purpose for wl'ii-ch it is intended by reason of the fact that it places the ventilation of each individual berth under the control of the occupant thereof and by reason of the fact that the method of adjustment and regulation is very simple in construction and may be very readily applied to the structure of Pullman cars new in use. it will furthermore be obvious that the specific era ample of my invention hereinbefore set forth is capable of many changes and modifications without in anymanner departing from the. spirit of my inven ion and I accordingly do not limit myself to such specific strudture except as hereinafter claimed.
